The ratio of radiant energies radiated per unit surface area by two bodies is `16 : 1`, the temperature of hotter body is 1000 K , then the temperature of colder body will be

The law which relates the energy radiated per second by unit area of a body and fourth power of absolute temperature of body is

The law which relates the energy radiated per second by unit area of a body and fourth power of absolute temperature of body is

A black body emits radiations of maximum intensity at a wavelength of Å 5000 , when the temperature of the body is 1227^(@)C . If the temperature of the body is increased by 1000^(@)C , the maximum intensity of emitted radiation would be observed at

A black body emits radiations of maximum intensity at a wavelength of Å 5000 , when the temperature of the body is 1227^(@)C . If the temperature of the body is increased by 1000^(@)C , the maximum intensity of emitted radiation would be observed at

A black body emits radiations of maximumm intensity at a wavelength of 5000 A^(0) , when the temperature of the body is 1227^(@) C. If the temperature of the body is increased by 1000^(@) C, the maximum intensity of emitted radiation would be observed at

The shows a radiant energy spectrum graph for a black body at at temperature T If the temperature of the body is raised to a higher temperature T then choose the correct statement (s).

The amount of thermal radiation energy emitted from the surface of a body is found to be proportional to the ........ power of the absolute temperature of the body.

Heat energy flows from a body at low temperature to a body at higher temperature.
